Teaching and learning software design patterns (DPs) is not an easy task. Apart from learning individual DPs and the principle behind them, students should learn how to apply them in real-life situations. Therefore, to make the learning process of DPs effective, it is necessary to include a project component in which students, usually in small teams, develop a medium-sized software application....

Vibrio cholerae is the causative agent of cholera, a dehydrating diarrheal disease. This Gram-negative pathogen is able to modulate its gene expression in order to combat stresses encountered in both aquatic and host environments, including stress posed by reactive oxygen species (ROS). In order to further the understanding of V. cholerae's transcriptional response to ROS, we performed an RNA s...

Fertilization exceeding crop requirements causes an accumulation of phosphorus (P) in soils, which might increase concentrations of dissolved and colloidal P in drainage. We sampled soils classified as Typic Haplorthods from four fertilization experiments to test (i) whether increasing degrees of phosphorus saturation (DPS) increase concentrations of dissolved and colloidal P, and (ii) if criti...

Discriminatory Processor Sharing (DPS) policy introduced by Kleinrock [5] is of a great interest in many application areas, including telecommunications, web applications and TCP flow modelling. Under the DPS policy the jobs priority is controlled by a vector of weights. Verifying the vector of weights, it is possible to control the service rates of the jobs and optimize system characteristics....

Dropped pronouns (DPs) are ubiquitous in pro-drop languages like Chinese, Japanese etc. Previous work mainly focused on painstakingly exploring the empirical features for DPs recovery. In this paper, we propose a neural recovery machine (NRM) to model and recover DPs in Chinese, so that to avoid the non-trivial feature engineering process. The experimental results show that the proposed NRM sig...

This paper analyzes the information-theoretical security of the Differential Phase Shift (DPS) Quantum Key Distribution (QKD) protocol, using efficient computational information geometric algorithms. The DPS QKD protocol was introduced for practical reasons, since the earlier QKD schemes were too complicated to implement in practice. The DPS QKD protocol can be an integrated part of current net...

Background. The aim of our study was to identify risk factors for developing active tuberculosis in regular haemodialysis patients (Dps). Methods. A 36-month follow-up of 272 Dps, in S/W Greece, where all new cases of active TB were detected. Eligible Dps were tested with tuberculin (Mantoux skin test), in a 2-step manner. Specific Relative Risks (RR) for TB was calculated considering subjects ...

Potential Search (PS) is an algorithm that is designed to solve bounded cost search problems. In this paper, we modify PS to work within the framework of bounded suboptimal search and introduce Dynamic Potential Search (DPS). DPS uses the idea of PS but modifies the bound to be the product of the minimal f -value in OPEN and the required suboptimal bound. We study DPS and its attributes. We the...

Reactive oxygen species can damage most cellular components, but DNA appears to be the most sensitive target of these agents. Here we present the first evidence of DNA protection against the toxic and mutagenic effects of oxidative damage in metabolically active cells: direct protection of DNA by Dps, an inducible nonspecific DNA-binding protein from Escherichia coli. We demonstrate that in a r...
